The SD1500 series asynchronous data serial server is a product produced by Shanghai Yuling Communication Equipment Co., Ltd. This series of products has the features of supporting subnet mask, UDP protocol, and Break signal. It also supports TFTP and Advanced Management. The document also introduces the use of SD1501/SD1502Lite.
The SD1500 series is an asynchronous data serial server that converts RS‑232 serial data to Ethernet for industrial automation and remote monitoring. It provides multiple RS‑232 ports, a 10/100 Mbps Ethernet interface, and supports common network protocols such as TCP/IP, UDP, TFTP and Telnet.
The document covers hardware description, serial port settings, management interfaces (Telnet, UART, TFTP), file transfer methods (Ymodem, Xmodem), and detailed configuration parameters like baud rate, data bits, parity and stop bits. This manual is written in Chinese.
